-WINDING MECHANISM FOR MUSICAL INSTRUMENTS. I

Application filed February 5, 1915.

To all whom it may concern:

Be it known that I, WVALLAon C. HILL, a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain n'w and useful Improvements in Winding Mechanism for Musical Instruments, of which the following is a specification, reference being bad therein to the accompanying drawing.

My invention relates to a winding mechanism for musical instruments, and I declare the following to be a full, clear, concise and exact description thereof suflicient to enable anyone skilled in the art to which it appertains to make and use the same, reference being had to-the accompanying'drawings in which like-reference characters refer to like parts throughout the specification.

The object of the-invention is to provide an efficient, simple mechanism adapted for winding up the motor spring of a phonograph or music box by the use of a lever actuated in a horizontal plane in contradistinction to the turning of a crank, as has been employed heretofore. The actuation of a ever in a horizontal plane, whereby to wind up the main spring is much easier than the old manner of winding or turning a crank. This object is disclosed in the drawings in which,

Figure 1 is a perspective view of a musical cabinet, containing the improved Winding mechanism; Fig. 2 is a side elevation of a member and pawls employed, the same bein reat-l cnlar ed' Fi 3 is an enlar ed 87 2D 23 7 t; b

Referring more particularly to the drawings, a cabinet or music box is represented by 1 the same having a top 2, hinged in the usual manner, so that it can be thrown back by the handle 3. The cabinet has also Specification of Letters Patent.

the front door 4:, which is hinged to the walls of the cabinet -1 in the well known manner. Near the upper portion of the cabinet 1, in the wall thereof, is a long narrow slot 5, adapted for the projection of the handle 6, provided with an angular portion 7 secured to the member 8 having the horizontal parts 99 from which arise the studs or members 10-10. To the studs 10, are pivotally mounted the dogs or pawls 11-11, adapted to alternately engage or fall by gravity into the open spaces 40 between the links 11 of the endless sprocket chain 12, which runs over the sprockct'wheels 13 and 14. The sprocket wheel 13 is loosely mounted upon a shaft 15 having hearings in the standards 16-16. The sprocket wheel 1% is mounted upon the shaft 60 having bearings in the standards 17-17 and is in mesh with the smaller gear wheel or pinion 18. The pinion 18 is keyed or otherwise secured to the shaft 19, so as to turn therewith. The shaft 19 is supported in the bearing in the tandard 20 and has attached in a rigid mannerto its opposite end a spur gear 21 in mesh with the spur gear 22 keyed to the shaft 23, so as to turn therewith. The shaft 23 is adapted for the securing of one end of the main spring 24. The other end of the main spring 2-l is fastened to the casing 25, mounted within the upper portion of the cabinet 1. The shaft 23 is held in the bearings of the standards 26-26 and has fixed to its opposite end a spur gear 27 adapted for rotating the other gears that are employed for turning the disk or cylinder of the phonograph or musical instrument, in the well known manner of the art.

A member 28 having a curved end 29 and a threaded end 30 is projected through a suitable recess in the member 8 and in the adjacent portion 7 of the handle 6, whereby the curved end 29 may securely hold a sleeve 81, which is adapted to slide along the bar 32 embedded at either end in the walls of the cabinet 1. The member 28 is, held in assembled position by the nut 33.

A coiled spring 34: is fastened at one end to the wall of the cabinet 1 and at its other end to the member 8, which is provided with the aperture 35 for the purpose,

so that when the handle 6 is manually pulled and released in the direction indicated by the arrow 36 in Fig. 5, the spring 34 will automatically return the handle 6 to its original position as illustrated in Figs. 1 and 5.

The operation of the device is effected by manually pulling on the handle 6, which is formed ataan angle of about sixty degrees to its horizontal portion 45, whereby to aid in giving a better leverage. As the handle (3 is pulled in the direction indicated by the arrow 36 in Fig. 5, the free end of the lower pawl 11 will'automatically drop by its own gravity into the open space 10 adjacent of the chain 12 and thereby force the chain 12 in the direction indicated by the arrows in Figs. 5 and 6. Simultaneously with the engagement of the lower pawl 11 in the open space 40 of the chain 12, the upper pawl 11 will ride freely over the links of the chain 12, as illustrated in dotted lines in Fig. until the handle 6 has reached the limit of its forward movement, which limit is adjacent the periphery of the sprocket wheel 14. Immediately the manual pull upon' the handle 6 is released, the same will return to its original position because of the tension of the coiled spring 34:. As the handle 6 begins to return, the free end of the upper pawl 11, will automatically drop by gravity into the open space 40 adj aeent to the chain 12 and thereby continue to actuate the chain 12; without any interruption, in the, direction heretofore mentioned as indicated by the arrows in Fig. 5. In this latter movement, the lower pawl 11 will ride freely over the links of the chain 12. The actuation of the chain 12 causes the sprocket Wheel 141- to revolve and thereby turn the pinion 18, which in turn causes the shaft 19, the gear 21, the gear 22, and the shaft 23 to revolve, whereby the main spring 21 is Wound up to run the disk or cylinder parts of the phonograph or musical instrument. The horizontal reciprocal movement ofthe handle 6 is guided by the bar 32 to which it is intermediately connected by the sleeve 31 and the member 28. The member 28 is adapted to permit a limited amount of movement of the handle 6 in relation to the sleeve 31, whereby the sleeve 31 will not bind upon the bar 32. -when the handle 6 is being manipulated.

Fig. 6 illustrates a certain modification in that a handle 50,,fixed to the end of a bar 51,-projecting in a sliding manner, through an aperture in the wall of the cabinet 1 is employed to draw the member 28 against the tension of the spring 31. The bar 51 is formed with a long narrow recess 52, which loosely receives a headed bolt 53, secured to the member 28.v .Obviouslyby pulling and relea'singthe handle 50, the chain 12 will be actuated as heretofore described. The recess 52 permits the bar 51 to be pushed back into the cabinet l, when the main spring 24: has been wound to its maximum limit and the member 28 having the pawls 11 is adjacent the near side of the cabiof the reciprocation of the handle 6, when the hand of the operator is withdrawn from the handle 6.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
